Indentations

Indentations from the left margin should be made up of tabs. Please to not use
space characters as mixing spaces and tabs gives ugly results when people use
different sizes for tabs. Throughout this documentation tabs will be represented
by an underscore followed by three spaces in order to make them clearly visible
on the page. Here is a example:

Apart from the indentation, please notice that there is one and only one empty
line between each top-level construct of the class, and also between features in
feature clauses.

(Borrow the guidelines from OOSC2 section 26.5 page 891. Note that contrary to
the guidelines in OOSC2, the recommended layout for
Gobo Eiffel classes in to put the class name on the
same line as the class keyword
— see class BAR above.)
